I decided to go vegan this month, I had already cut things like dairy and eggs before but now I definitely eat only vegan food. The problem is that I'm really scared of getting fat and eat too many calories. I had already this problem but now is more evident and my parents won't allow me to eat vegan anymore. They think that if I ate small portions of meat and eggs I will be healthier even if I don't eat a normal quantity of food, I really don't know what to do...
